Fewer doubts. Better decisions.
FranjaLuz turns official prices into clear, useful information for everyday life.
Tomorrow’s estimate
Tomorrow’s price, before it’s published
Red Eléctrica publishes tomorrow’s prices at around 20:15. Until then, FranjaLuz estimates each hourly price so you can plan ahead.
- From 6:00, indicative; from around 13:30, based on wholesale market prices
- Set an alert on any estimated hour: it updates itself to the official price
- Estimated vs. actual: see day by day how accurate we’ve been
It’s an estimate, not the official price: once REE publishes tomorrow’s PVPC, it takes over.
Self-consumption
Got solar panels? See what your surplus is worth too
Turn on Self-consumption and FranjaLuz shows, in purple next to the consumption price, the surplus compensation price for every hour: the official one for PVPC with simplified compensation.
- The surplus price, in purple, next to the consumption price
- All 24 hours in the chart and in the list
- One tap to turn it on or off in Hourly price
We only show prices: FranjaLuz does not connect to your panels, measure your production or calculate your bill. On a free-market tariff, the surplus price depends on your contract.
Alerts
We notify you before the best hour begins
Automatic alerts, the hours you pick or your own reminders, with the notice you prefer and only when you’re in your zones.

Before saving, you can send yourself a test alert to see how it arrives.

Electricity generation
Where does your electricity come from?
For every day, how much electricity was generated and from what: wind, solar, nuclear, hydro, combined cycle… FranjaLuz separates renewable from non-renewable, with data from Red Eléctrica.
- Renewable and non-renewable, technology by technology
- The day’s demand, exchanges and CO₂ emissions
- Every day since 2011, with official REE data
Days in the current and previous month are provisional: REE may revise them, and FranjaLuz picks up those revisions when it updates.
Apple Watch
The price on your wrist, without reaching for your phone
Check the current band and the hours ahead from the watch, and keep the FranjaLuz card in the Smart Stack, right under the face.
Personalisation

Dynamic mode shifts the background with the time of day: morning, midday, afternoon and night. You can also lock it to light or dark.
